ObjectiveTo explore the efficacy of calcitonin combined with glucosamine hydrochloride on knee osteoarthritis. MethodsAccording to Kellgren-Lawrence radiographic scoring system, 156 patients with knee osteoarthritis diagnosed from November 2014 to April 2015 were classified as mild, moderate and severe cases. All of the patients were divided into control group (treated by glucosamine hydrochloride only) and trial group (treated by calcitonin combined with glucosamine hydrochloride) via table of random sampling numbers (with 78 patients in each group). The West Ontario and Manchester University (WOMAC) score was recorded at the 6th week and the 3rd month after the medication treatment. ResultsIn the patients with mild osteoarthritis, there were significant differences in WOMAC score of both groups at the 6th week and the 3rd month after treatment compared with those before the treatment (P<0.05); there were no significant differences between the two groups at the same time points after the treatment (P>0.05). In the patients with moderate osteoarthritis, WOMAC scores in the control group at the 3rd month differed much from that before the treatment (P<0.05); there were no significant differences between the two groups at the same time points after the treatment (P>0.05). In the patients with serious osteoarthritis, there was no significant difference in WOMAC scores in the control group after the treatment compared with that before the treatment (P>0.05); while in the trial group, the scores at the 3rd month after the treatment differed much from that before the treatment (P<0.05), and also from that in the control group (P<0.05). ConclusionFor mild knee osteoarthritis, the combined treatment is not superior to the single use of glucosamine hydrochloride. For moderate knee osteoarthritis, the combined treatment has faster effect than the single use of glucosamine hydrochloride. For severe osteoarthritis, the use of single glucosamine hydrochloride is not effective, while the combination of calcitonin and glucosamine hydrochloride is effective at the 3rd month after the treatment.
To assist grassroots sonographers in accurately and rapidly detecting intussusception lesions from children's abdominal ultrasound images, this paper proposes an improved YOLOv8n children's intussusception detection algorithm, called EMC-YOLOv8n. Firstly, the EfficientViT network with a cascaded group attention module was used as the backbone network to enhance the speed of target detection. Secondly, the improved C2fMBC module was used to replace the C2f module in the neck network to reduce network complexity, and the coordinate attention (CA) module was introduced after each C2fMBC module to enhance attention to positional information. Finally, experiments were conducted on the self-built dataset of intussusception in children. The results showed that the recall rate, average detection accuracy (mAP@0.5) and precision of the EMC-YOLOv8n algorithm improved by 3.9%, 2.1% and 0.9%, respectively, compared to the baseline algorithm. Despite slightly increased network parameters and computational load, significant improvements in detection accuracy enable efficient completion of detection tasks, demonstrating substantial economic and social value.
0bjective To investigate the prevalence of gastroesophageal reflux(GER)in acute exacerbation of chronic obstructive pulmonary disease(AECOPD)and to explore the influence of GER on the acidity of airway and pulmonary ventilation function in AECOPD patients．Methods Sixty-five hospitalized AECOPD patients and 20 healthy volunteers were enrolled in this study．According to “GER survey”questionnaire，AECOPD patients were allocated into GER group and non-GER group and expired breath condensate(EBC)pH and pulmonary ventilation function were detected．Breath condensate samples were collected using a specially designed condensing chamber(EcoScreen，Germany)．Results About 30.8％ (20／65)AECOPD patients were complicated with GER．EBC pH was lowest in GER group，middle in non-GER group and highest in the control group[6.oo±0.75 VS 6.76±0.77 and 7.97±0.12，both Plt;0.05)．The pulmonary ventilation function(FEV1、FEV1％pred)in AECOPD patients with GER were lower than those without GER(both Plt;0.05)．Conclusions There iS a high prevalence of GER in AECOPD patients．And the airway pH is reduced in AECOPD patients，especially when complicated with GER，which may play an important role in the development of COPD．
Surgery is an important method for the treatment of malignant tumors. Sevoflurane is one of the most common general anesthetics, which can directly or indirectly affect the biological behavior of cells and the immune function of tumor patients, thereby affecting the recurrence and metastasis of tumor patients after surgery. From the aspects of microRNA, matrix metalloproteinase, phosphatidylinositol-3-kinase/Akt signaling pathway and hypoxia-inducible factor-1α, this article summarizes the molecular mechanisms of sevoflurane affecting the biological behavior of tumor cells, and clarifies the regulation mechanism of sevoflurane on the immune function of tumor patients. It is expected to provide a theoretical basis for precise anesthesia for tumor patients, and to provide medication basis for reducing postoperative recurrence and metastasis of tumor patients.
ObjectiveTo explore the therapeutic effect of glucosamine hydrochloride combined with calcium and vitamin D on knee osteoarthritis. MethodsA total of 120 female outpatients with knee osteoarthritis from January 2014 to January 2015 were selected. The patients were randomly divided into study group and control group (60 patients in each group) according to their treatment sequence. The patients in the study group were given oral calcium citrate, alfacalcidol and glucosamine hydrochloride while those in the control group were given glucosamine hydrochloride only. Both groups were investigated and scored by Western Ontario and McMaster University Osteoarthritis Index (WOMAC) questionnaire before and three and six months after treatment. ResultsThree and six months after the treatment, WOMAC scores of both groups were lower than those before the treatment with significant differences (P<0.05). Three months after the treatment, WOMAC scores between the two groups didn't differ much (P>0.05), while the difference between the two groups was significant 6 months after the treatment (P<0.05). Three months after the treatment, the difference of total effective rate in the study group (43.3%) and control group (41.7%) was not significant (P>0.05), while the rate in the study group (65.0%) was obviously higher than that in the control group (46.7%) 6 months after the treatment (P<0.05). ConclusionGlucosamine hydrochloride has exact effect on knee osteoarthritis. There are differences in the therapeutic effect on knee osteoarthritis between glucosamine hydrochloride combined with calcium and vitamin D and glucosamine hydrochloride alone after six-month treatment.
Objective To discuss the early diagnosis and surgery of intestinal necrosis caused by superior mesenteric venous thrombosis （SMVT）. Methords The clinical data of 32 patients with intestinal necrosis caused by SMVT were reviewed retrospectively and analyzed, which included 6 cases of primary SMVT, 26 cases of secondary SMVT, 9 cases with pylethrombosis, 24 patients had been dignosed definitely as SMVT by imageology examination before surgery. All the patients accepted surgery therapy, within which 9 patients accepted Fogarty catheter, and anticoagulation and thrombolytic therapy were administrated postoperatively. Results All patients had recovered except for one with short bowel syndromle and one died. Conclusions SMVT is a rarely ischemic intestinal disease, which has complicated pathogenesis and difficulty in early diagnosis. Intestinal necrosis often occurs as a result of delayed treatment and the effective way is to cut off necrotic intestines in time. Intra-and postoperative anticoagulation and thrombolytic therapy could reduce recurrency effectively.
目的 總結頸動脈體瘤的診斷和外科手術治療的經驗。 方法 分析我院1991年9月至2009年2月期間手術治療的16例頸動脈體瘤患者的臨床資料。 結果 術前均行彩色多普勒超聲檢查，9例行CT檢查，6例行數字減影血管造影檢查。3例首診時誤診為其他疾病。11例行單純瘤體切除； 5例采用大隱靜脈行頸動脈重建。術后1例出現聲音嘶啞，1例出現伸舌右偏，1例出現呼吸困難。10例獲得7個月～15年（平均67個月）隨訪，未見復發和轉移。 結論 臨床醫師應提高對頸動脈體瘤的認識,注意選擇合適的檢查方法以免誤診，外科手術切除是首選的治療措施，大隱靜脈重建頸動脈是一種較安全、有效的治療方法。
